Fix commit SHA checkout and add enhanced run context

- Fix git checkout failure when testing specific commit SHAs
- Use conditional fetch depth: shallow for auto runs, full for manual
- Add explicit commit fetch and checkout for manual runs
- Enhance run-name to show commit SHA for manual tests
- Add detailed commit info display with author, date, and changed files

Fixes issue where actions/checkout@v4 treated commit SHA as branch name
